ON-LINE COMPUTER CONTROL SYSTEM

摘要

The disclosure of this invention pertains to a control system for two gas turbine engines each having two identical sets of control transducers. Each engine is associated with a digital computer programmed for controlling the fuel flow of the engines. The computer is associated with means for being de-powered in the event of a fault in the computer or a fault completely preventing communication with the engine. Also each computer has means for sensing if the other computer is not on power and, if so, assuming control of the other engine through a switching system for connecting the one computer to either engine. The computer is also programmed, in the event of a fault in a transducer of the one set of transducers of whatever engine it is controlling to operate the switching system to gain access to the corresponding transducer of the other set.
